All of us are aware that a marine air conditioner is becoming one of the most important pieces of equipment for all sorts of boats. Is an expensive accessory, and before purchasing is important getting proper advice to know about those details that will turn an air conditioner into a long lasting equipment, without faults and providing the most comfortable environment without noise.

By reading this guide, you will be able to differentiate like an expert, all the details that make our air conditioners some of the best in the market.

- CuproNickel condenser is the most distinctive component of a marine air conditioner. All the seawater used to remove the heat from inside the boat cabin will run trough the condenser. Must resist corrosive seawater, and needs to be built with an special CuproNicker 90/10 alloy.
- We use coaxial tube condensers, that are the best type for this purpose. One of the key aspects of this type of heat exchanger is that are built without weldings in the inner tube. Weldings are weak points against corossion, and by removing them will increase its durability.
- Besides our condensers are made with internal corrugated tube that improves system efficiency by an optimum heat transfer ratio and the smallest size. To maintain the best appearance, we coat its outer tube with paint.

- Refrigerant compressor is also one of the key elements of a good air conditioner. Has big influence in high efficiency, durability and LOW NOISE NEVEL. For many years the unbearable amount of noise produced by marine air conditioners was their worst handicap. Concerned about its importance, we only use a selection of the best compressors in the market. They are so quiet that can even be installed under a bed without affecting your sleep.  
- Being rotary type, their inrush current isn't so high as in alternative compressors. This is particularly useful when the air conditioner is to be used with a genset or if its to be used in marinas with scarce power supply.

While producing our air conditioners, we pay special attention to use the best evaporators. Built in copper and high quality anodized aluminium, to benefit from maximum durability and excellent heat transfer. We also pay careful attention to their aspect, avoiding deformations and scratches.
We never apply paint to the evaporators, because that would affect negatively to their heat transfer efficiency. Suspect from those air conditioners with painted evaporator, as normally that paint has been applied by the producer for hiding its bad quality.

Another difference of our evaporators is that we weld by numeric control CNC, to improve quality and reduce the possibility of meeting refrigerant gas leaks. 

All our systems have built in washable air filter, that is also an additional advantage. Other producers don't use these filters, and as time goes by, will cause dirt accumulation on the evaporator surface and consequently reduced cooling power. A clogged evaporator can also cause low pressure problems working as air conditioner or high pressure when working as heat pump.

- All our climate systems use blowers with the newest technology. Are fitted with programmable speed control according to the specific requirements of each installation. Internal motor to achieve the most compact size. We use balanced turbines for a minimal amount of noise and low vibration. High static pressure to be used on those cases when the air duct is long and complicated. 
- For installation easiness, the blower can be rotated, matching the requirements of any boat.

Reliable electronics

For a marine air conditioner to achieve optimal functionality, needs to be controlled by an electronic circuit specifically developed for marine use. Our electronic control has been specifically designed for marine use, incorporates all the necessary functions, and also all sorts of electric safety features.

All our machines have 4 way valve to allow usage in winter as heat pump. Once you invest in purchasing and installing an air conditioner in a boat, is always recommended having the possibility to use it in winter as heater.

slim design

Slim design for installation easiness

One of the most difficult parts of the installation in a boat can be finding the necessary space for holding the machine. Aware of this important restriction, we have incorporated an optimized design, to achieve the most compact footprint in the market. Its slim design makes much easier its installation under seats and other reduced spaces.


high pressure sensor

evaporator temperature sensor

Evaporator temperature sensor

Its VERY IMPORTANT constantly monitoring all equipment working parameters, so in case anything goes wrong the system will be disconnected immediately, preventing expensive repairs.
All our machines have several safety devices to perform this task:
- High pressure sensor- Several external situations can cause high pressure inside the refrigerant circuit, like for instance a fault or a blockage in the pump.
- Evaporator temperature sensor- In case of reduced air flow, ice could build up in the evaporator surface, damaging it.
- Over and Under voltage- In very touristic areas that attract an unusual amount of visitors in summer, voltage is typically very unstable. Our systems are well protected against this problem that could cause severe damage to its electrical components.
- Compressor start delay- It could happen that the compressor might be required to start and stop too frequently. The compressor would suffer enormously because of the high inrush current, and is necessary to protect it.
- Compressor overload- In case everything else may fail, our compressors always have a redundant protection against overloads


high quality weldingsWelding's quality is one of the best indications of the level of quality that a refrigeration machine has. One of the most common faults in bad quality air conditioners are refrigerant leaks. To prevent this type of problem, we apply very precise weldings performed with high quality materials. The appearance of the machine is very neat and clean. Other producers who can't achieve the proper level of quality, will paint the pipes after welding, trying to hide their poor fabrication procedure.


vacuum test and refrigerant loadOur air conditioners meet all the requirements from current European norm and hold CE mark.
In our production we use environmentally friendly refrigerants type R134a or R410a.
Once finished all pipe weldings, and to detect possible leaks, we undertake a vacuum test for at least 24 hours. Once the test is completed, the circuit will be loaded exactly with the right amount of refrigerant that it needs and the circuit will be sealed. This way you will receive your new machine already filled and ready to use, so that its installation will be very easy because will not require assistance from any refrigeration technician.

According to the protocol stated in the norm, avery single machine undertakes a rigorous safety test, that will ensure proper functionment and electrical safety of the machine.


stainless steel drain panAll our self contained units are built on AISI316 stainless steel drain pan. No escatimamos en espesor de la chapa ni calidad del material, lo que aporta al conjunto una construcción muy robusta y duradera frente al corrosivo ambiente marino.

Otros fabricantes intentan abaratar costes, utilizando bases de plástico que resultan más frágiles o de acero convencional pintado que pronto sufrirán los efectos corrosivos del ambiente marino


power supply frecuency depending countryNuestros aires acondicionados realmente entregan la potencia indicada. La mayoría de fabricanets de aires acondicionados marinos utilizan compresores versátiles que pueden funcionar con frecuencias de 50 y 60Hz. De este modo evitan la necesidad de almacenar 2 tipos de compresores diferentes y aprovechan los mismos productos que venden en Estados Unidos, para la venta en Europa. El problema es que la frecuencia del suministro eléctrico en Estados Unidos es de 60Hz, pero en Europa el suministro eléctrico es de 50Hz. Evita el engaño de comprar una máquina que indique 230V 50/60Hz porque son máquinas que pierden un 20% de su potencia al utilizarse en Europa con suministro eléctrico de 50Hz.
